To oZZ-leho/n-z'tmay cancer-m Bait known that I, JOHN HoL'rz AN a cit zen. of the 'United,Statesresiding at of sewing machines,

Baltimore, State of i, Maryland, have lIll'. vented or dlSCOVeI'QCl certain new and useful Improvements in Sewing- Machinei Folders, of which the" following is a "specifica-tion, reference being ad therein to'the acconlpanyingdrawings' This invention relates tofolders. for turn ing in the edges of strips of fabrictojbe" presentcd to the stitch-forming mechanisms and is more particularly'intended for use in connection with two needle sewing [machines adapted to simultaneously form two parallel rows of stitching, although the invention may be -nsed. in connection-with singlejneedl'e ma-f chines, but not to the same advantage,

. In doing some k nds of work, as nforming straps and belts, or making loops such as are commonly attached to the tops of trousers for holding belts, tice to. turn in the two opposite edges fof two strips of fabric which are su 1er posed upon eachother, as they are presented to the stitchrforming mechanism". ofa two-needle sewing machine, so that the turned-in edges will be stitched down within the bodies of, the strips, thusfforming I belt or loop with turned-in edges. By the use of the present] invention a two-ply strap, belt, onloop, such as 'just referred to, may be formed from, a single strip of material having the edges turned in, and

which is doubled upon itselfas it is pre sented to the stitch-fiormingmechanism .of a-tWo-seedle sewing machine, thereby forming a two-ply strapbelt or loo-phav-ing a finished end; and if the stitched strap be h intended for a suspender strap abuckle may be stitched into such finished end infthe 1 operation of formingthefstrap, as willhere- -1uafter appear.

In carrying the invention into effect a folder which is adapted tot-urn in the opposite edges of. a strip of fabricis provided at its forward end with ahinged section, so that when a strip of fabric has been drawn through the folder fto theextent of about one-half its length itinay 'be'ldoubled upon itself in "such a} manner that" the turned-in edgesof both parts or plies of the doubled strip will be inside of such doubled strip, and thestrip may then- 'be presented to the stitch-formingmechanism 0f atwo-needle sewing machinein such a X Specification of Letters i a tent. v I I Application filed t me 10,1912. serial No. 714,429.

Attached to the forward end-of the body-of the folder, either by a singlecentrally' disposed hinge 15, or one "ortwo side hinges 1 6,- is'a folderseotion 17 having at its opposite edges scroll portions 18 which,'-'when the'hinged section at its opposite is in line with the body of the, folder, practically form continuations of the forward,

ends of the scroll sections 13, ,so, that a strip of fabric may be drawn. through the folder When the hinged section is, in line P lPQ through the folder, as 7 indicated in "Fig. l,

The folder 12 is preferably solder or otherwise, to a plate 919', which is secured, by

in turn pivotally attached to a plate-20 l which may be one of the slides covering the shuttle race of the sewing machine, and which will, in such case, be held in place onthe machine by theguides for such slide, in a well-known manner. This ivotal connection of the folder with its ho ding.plate 20 enables the folder to be swung aside as shown in full lines in Fig. 1, for the insertion of the work-,and to be swung hack to its operative position after the work has been inserted and the hinged section has been turned over onto or under the body of the folder, as denoted in dotted lines in Fig. 1, and as also shown in Figs. 2 and 4. When the folder is thus swung into operative position its forward end will be closely adjacent to the presser foot of the machine, so that the doubled stri with its folded-in edges, when pulled s ightly through the folder, may be readily engaged by the feed of the machine and carried to the stitchforming mechanisms. In Fig. 2 the position of the presser-foot as relative to the folder is denoted by dotted lines, and the positions of the needles by the dots 11; To insure a proper positioning of the folder, when thus swun into its operative position, a stop, afforded y a pin 21 on the plate 20 and arranged to engage a recessed part 22 on the plate 19, is' preferably provided. When a strip of a certain length has been drawn through the folder to an extent which will bring its middle portion opposite the hinge connecting the hinged section, the

body of the folder is turned over either onto or under the body of the folder so as to form a double-ply strip both edges of which are turned in adjacent to each other within the folded strip; andthe folder, which has been swung aside as denoted in full lines in Fig. 1, for the insertion of the work, is then swung back to the position denoted in dotted lines 1n Fig. 1 for the stitch-forming operation.

If it be desired to insert a buckle into the strip to be stitched, as informing a suspender strap, the folder may be supported .in any suitable manner above the workplate, and with its hinge on the lower side of the body of the folder, as shown in Figat.

. With this arrangement the loop or bail of a buckle may be disposed in a small recess at the forward end of the body or main section of the folder in such a manner that when a.

strip is drawn through the folder it will pass through the said loop or bail of the buckle between the main and hinged sections of the folder; and when the folded strip has been drawn through the folder to a desired extent the strip, with its folded-in edges,

will be doubled upon itself by turning in the hinged section of the folder beneath'the 91 this patent may be obtained for live cents each, by addressing the "Commissioner of Patents,

body thereof. so that when-the doubled strip has been stitched down the buckle will be held in place in the strap thus formed by such doubled strip, when the plies of the same have been properly stitched together.

If it be desired to' attach a two-ply strip with its folded-in edges to a piece of fabric, as where such doubled stitched strip would form a plait on or a finish for such piece of fabric, the piece of fabric may be interposed between the main and hinged sections of the folder in such a manner that a centrally disposed hinge, as 15, will serve as an edge guide for the piece of fabric, which may then be carried forward between the two plies of the strip and will be stitched in between them in the stitch-forming operation.

The invention is not to be understood as being limited to the details herein shown and described, as these details may be varied, within the limits of mechanical skill, without departing from the essence of the invention.

Having thus described my invention I 7 claim and desire to secure by Letters Patent:

1. A sewing machine folder having turning scrolls at its opposite edges and pro vided at its forward end with a hinged section having scroll-portions practically forming continuations of the scroll portions of the said folder.

2. A sewing machine folder having turning scrolls at its opposite edges and pro-.

vided at its forward end with a hinged section having scroll portions practically forming continuations of the scroll portions of the said folder, combined with a support or holder with which the said folder has a pivotal connection, so that it may be, swung asidefor the insertion of the work, and may then be swung back to its operative position.

3. A sewing machine folder having turning scrolls at its opposite edges and provided at its forward end with a hinged section having scroll portions practically forming continuations of the scroll portions of.

the said folder, combined with a support or holder with which the said folder hasa pivotal connection, so that it may be swung aside for the insert-ion of the work, and may then be swung back to its operative position, and a stop for limiting the swinging movement of the said folder, and for propgr l y.

positioning the same, when the latter is" swung into its operative position.

In testimony whereof I aflix my signature,

in presence of two witnesses.
